Image processing with Python-resizing a picture

Python has an image processing library--pil that can process image files. PIL provides powerful methods such as format conversion, rotation, cropping, resizing, pixel processing, picture merging, and so on.

For a simple example, adjust the size of the picture:

Import imageinfile = ' d:\\original_img.jpg ' outfile = ' d:\\adjust_img.jpg ' im = Image.open (infile) (x, y) = im.size #read ima GE sizex_s = #define Standard widthy_s = y * x_s/x #calc height based on standard widthout = Im.resize ((x_s,y_s), Ima Ge. AntiAlias) #resize image with High-qualityout.save (outfile) print ' original size: ', x,yprint ' adjust size: ', x_s,y_s ' Output:original Size:  358adjust Size:  250 179 "
